An efficient synthetic protocol was devised for the synthesis of 3,5-disubstituted 2,6-dicyanoaniline from malononitrile, aldehydes, and β-nitro-olefins by using N,N-dimethyl-4-aminopyridine (DMAP) as a nucleophilic catalyst. The important aspects of the present methodology are: use of non-toxic organo-catalyst, shorter reaction time, compatibility with wide range of substrates, and good yields.
通过使用N,N-二甲基-4-氨基吡啶(DMAP)作为亲核催化剂,设计了一种有效的合成方案,用于从丙二腈,醛和β-硝基烯烃合成3,5-二取代的2,6-二氰基苯胺。本方法的重要方面是:使用无毒的有机催化剂,较短的反应时间,与多种底物的相容性和良好的产率。
